EARTH-HANDLING EQUIPMENT.

Application filed July 20, 192a.- Serial naesa'ras.

This invention relates to grading or exc avating apparatus.

This invention has utility as a plurality of power actuated drag lines, and the mounting and manipulation thereof.

Referring to the drawings:-

Fig. 1 is a side elevation of an e1nbodiment of the invention mounted upon a structure;

Fig. 2 isa front elevation, with parts broken away, oi the device of Fig. 1;

Fig. 3 is a plan view with parts broken awa Fig. 4- is a detail view of a drum; and

Fig. 5 is a fragmentary end View of the drum of Fig. 4. 4

Tractor 1 is shown ashavin front side 3 andrear axle i. The rear axle 4' has housing 5 upon which rest uprights 6 fixed in position as to the housing 5 by bolts 7 engaging lower clamping sections 8.

These uprights 6 extend to deck or platform 9. The front axle 3 above trunnion pin 10 in member 11 has bolt 12 through opening 13 above this trunnion pin 10. This bolt '12 rockably mounts transom bar 14 over the axle 3. This rockablefront transom member 14 has from its upwardly offset termini risers 15 to deck or platform 9.: According ly, the two supports 6 and the bolt; 12 provide three-point support or hearing for the platform 9, thereby allowing the tractor in worm 26in mesh with wormvwheel 27 fixed- 13* mounted on shaft 28 in bearings 29 30,

carried by the frame 25.

Between the bearings 29 and 30 this shaft 28 has pinion 31 and clutch member 32' fast therewith. HThis clutch member 32 is in opposin' relation to clutch member 33 fixed with rum 34 iooselymounted onthis shaft 28. From the bearing 30 risev ears 35 carry- I ing fulcrum pin 36 for lever 37 having hand1e38'at one extremit and at the other extrernity having vfdrkie portion 39 carrying rollers 40 ridingifiin groove 41 'housed by flange 42 of the. drum 34. The hearing 30 motor 2,

below the shaft 28 has a sec'oind fulcrum pin 43 forlever44-having treadle portion 45 at an ojperators station beiow the handle 38. The opposite'end of this lever 43 has brake. shoe portion'46 effective on depression of the treadle 45 to'be thrown into frictional retarding relation with the flan e or brake drum 42 of the Windlass or cab ie carrying drum '34. Thelevez" 37 is normally thrown into notch 47 of cross bar 48 carried by the frame 25. This drawing or tilting of the lever 37 is etiected againstthe action of ten sion spring 49 extendingacross the Windlass structure from the lever 37 to bar 5.0 of the frame 25. 5

The pinion31 is in mesh with pinion 51 I i on shaft 52 in'bea rings 53, 54, carried by the gear-31 is in mesh-with gear 5.5 on shaft 56 mounted in bearings 57, 58, carried by the frame '25. These "shafts v52, 5%, are in a common plane belowI-the-level of he shaft 28. of these shafts- 52, 56, has clutdh. and drum construction -v together with controls therefor in the way: of clutch levers the frame25. These bearings 53,. 54, dis-' 1 37 andffoot brake leversi44. Betweeii the I bearings'29, 53, is the :turn buckle. tie structure 59. There is-f1iiso such brace 01' tie" between the" bearing 29 and the bearing 57 as well-as between the hearing 30 -and the bearing 54,:and' the hearing 30 and the bearing 58. Thi-smeans, that notwithstanding these areseparate bearings as mounted upon the common frame 25;, there isan additional adjustable aligning means for maintaining the several drums of this multi-drum power driven indlass in rigid assembled relation. l

The frame 25' at its oppositeends, which are adjacent the sides of-the platform 9, has frame portions providing hearings ifor yer- 'tical guide rollers 60 andhorizontal; guide rollers 61. Thsefguiderollers-.are gassembledasopposite 'pairsito form an anti-fric- 'tion guide throafl tlirough which cable "from drum 34 or'iltheshaft 56 may extend. In the opposite direction-drum 34 ,on the shaft 52 may have means 63 extend through the otherguide throat.

In simple direct" operation this machine has great advantage in h'erining. There is considerablework of this eharacterin rural avin'g operations whereinloose material is rought up more level of the concrete or stalled. In the drawing of this material directly up to the curl) of the pavement, the cables 62, 63, may be connected to slip scrapers 64 of the hand directed type. At operators station on the platform 9 the respective clutch levers 37 may be drawn into driving position against the action of the springs 49 to effect a drawing or pulling acting upon the drag lines in pulling scrapers full of loose earth up to the vicinity of the pave ment, At once upon release of the hand lever 37, the pulling operation ceases. The foot brake 45 be used to steady the pull or stop feed c draft. At once the draft is stopped, the Workman directing the filling andfdumping of the drag line scoop or scraper fi l may pull such scraper down into the. ditch oraway from the pavement to be in readinessfor a succeeding scraping opera- 7 ation.

In practice, this vehicle with its power. may be shifted along the highway ipu'lley 66 and thence back by for drawing in the material and in those instances where there is inequality of distribution the'drum 34 on the shaft 28 may have its cable 65 extend through oneor the other ofthe guide throats as may be desired for pulling in the material from a region forward or rearwardlof the apparatus. This draft has inpractive been effective for as much as seventy-five or one away from the machine in road work opera-- tions. In more extended draft as for instance inditch'ng work, the cable 65 may extend past the scrapers 64 to a dead man or another reach to the drum 34 on the shaft28'with a scraper the load;
